We can use the formula P=VI, where P is the power in watts, V is the voltage in volts, and I is the current in amperes. Rearranging the formula, we get:

I = P/V

Substituting the given values, we get:

I = 60 W / 120 V
I = 0.5 A

So the current drawn by the light bulb is 0.5 A, which corresponds to choice B.
